I did not mean the new features that will be standardized in C++1x. They
are great, I'm really anxious to get my hands on many of them. But
that's not enough. Dynamic/static modules, properties, network and
asynchronous IO in general, binary serialization (portable between
different architectures), XML support - for a start. Let alone the holy
grail of GUI, even the most basic one. These things are there for ages,
and they are needed almost all the time. I understand that there are
great libraries, including Boost, but every other library added to the
project adds complexity, which is not required with other languages. For
some things there are no libraries for there's just not enough language
support (modules, for instance).

I agree that Boost.Log in particular is a very large library, and a few
weeks are not enough to fully evaluate it. On the other hand, it is
enough to evaluate the approach and architecture, and overall
implementation quality without diving too much into details.

Like I said in my post, if you're trying to base your decision on the
real world practice with the library, even 6 months of review are not
enough. It becomes not a review, but an active (or not - depends on the
demand in that particular time frame) usage of the library, which is
being held in a hanging state. Other people in this conversation
suggested that the library should be frozen during the review period. Do
you expect an author to be willing to freeze the library for 6 months?
Let alone for years in order to collect real world experience, as you

I understand and share your reasoning, but the solution you propose
doesn't look valid for me. It would be interesting to hear what you
think of the idea I expressed in my previous post - divide Boost into
stable core and experimental outskirts, with the accordingly matched
acceptance criteria.

Yes, but if the person has several review on his hands, the probability
of such situation gets higher.
